I have been building a simple desktop client-server app for sometime and am now working to build a saas/cloud business. I'm know html/css/javascript/asp/sql/etc, but building a 24/7 hosting business seems pretty intense, is there a good website that walks you through starting a saas business in 2012? I want to know about coding languages, hardware recommendations, security, multi-tenancy, backups, 99% uptime, etc. Thanks in advance! Micah
